With the blood pressure meter of the present invention, a pump unit is connected via a first fluid path to a fluid bladder. The first fluid path extends straight in the Z direction between the pump unit and the fluid bladder, sends air supplied from the pump unit to the fluid bladder or sends air inside of the fluid bladder to a valve.

Blood pressure meter

A first oscillation circuit and a second oscillation circuit are connected to a first pressure sensor and a second pressure sensor, respectively, and oscillate based on the capacity values of the corresponding pressure sensors. The first oscillation circuit and the second oscillation circuit operate in response to instruction from a CPU. The one of the first oscillation circuit and the second oscillation circuit that has received an activation signal from the CPU outputs a signal having a frequency that corresponds to the capacity value of the corresponding pressure sensor. An adjustment circuit is connected to the first oscillation circuit and the second oscillation circuit, and allows one of the frequency signals to pass therethrough, outputting the signal to the CPU.

Electronic sphygmomanometer

In an electronic sphygmomanometer, the thickness of the second connection tube is set to be lower than the thickness of the first connection tube, and therefore, even if error has occurred in the structural dimensions of the pressure sensor air tube, the error can be absorbed as a result of the second connection tube extending/contracting. It is therefore possible to provide an electronic sphygmomanometer that includes, in a structure in which a pressure sensor used in the electronic sphygmomanometer is disposed, a peripheral structure for the pressure sensor that can improve the reliability of blood pressure measurement values.

A blood pressure meter includes a cuff serving as a blood pressure measurement cuff, a main body attached in an opposing manner to the cuff, a display unit having a rectangular width and being arranged along an external face of the main body on a side opposite to the cuff, and first to third light emitting elements serving as light emitting units arranged inside the main body at positions that are farther from the external face than the display unit is. The first to third light emitting elements serving as a light emitting unit are arranged in a row in the width direction of the cuff. The display unit has a cutout portion at the center of one end side with respect to the direction in which the cuff extends. The cutout portion is formed by cutting out a region corresponding to the first to third light emitting elements.

In an electronic sphygmomanometer, a first pressure sensor and a second pressure sensor are disposed on a front surface side that serves as a first main surface of an internal circuit board, following a horizontal direction (the X direction) that is orthogonal to the direction in which the internal circuit board is sloped. As a result, the first pressure sensor and the second pressure sensor are disposed having the same height position. It is therefore possible to provide an electronic sphygmomanometer that includes, as a structure in which a pressure sensor used in the electronic sphygmomanometer is disposed, a peripheral structure for the pressure sensor that can improve the reliability of blood pressure measurement values.

In an electronic sphygmomanometer, a protruding member is provided in an outside surface of a first air port connection head, and when a first air port is pushed into the first air port connection head, the protruding member passes over a first shielding plate while elastically deforming and reaches a position on the inner side of the first shielding plate. As a result, the first air port connection head is prevented from pulling out from the first air port, and a sense of the protruding member locking in upon returning to its original form is imparted on a worker. It is therefore possible to provide an electronic sphygmomanometer that includes, as a structure in which a pressure sensor used in the electronic sphygmomanometer is disposed, a peripheral structure for the pressure sensor that can improve the reliability of blood pressure measurement values.
